The writer burns the first 256MB with 2.4X speed, which doesn't work well with these discs (a lot of errors in this area; quality scores average ~43% on Nero-DiscSpeed because of this)
So if you have this writer, DON'T buy these discs!
Or if you already bought them, think about creating a dummy file to put it at the beginning of the disc, so that your actual data gets written in the safe areas.
A good way of doing this in Windows is using the following command:
fsutil file createnew _dummy 275000000
